CLAMPING DEVICE FOR EMBROIDERY-FRAMES.

Application filed July 14, 1915.

To all whom it may concern:

Be it known that I, CHRISTIAN SCHOEN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Clamping Devices for Embroidery-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements in embroidery frames; and, the invention relates, more particularly to a work-holding frame and a novel workclamping means therefor, with a view of providing an easily manipulated embroldery frame in which the several pieces of work to be embroidered can be readily placed and clamped and retained in perfectly stretched relation, so that the work is held in smooth condition, when placed in the embroidering machine.

The present invention, therefore, has for its principal object to provide a simply constructed and easily manipulated embroidery frame, and work-holding clamp therefor, for fastening the work, such as handkerchiefs, and other articles of wear, and especially the corner-portion of the work, in position in a perfectly stretched and taut relation in the frame, so that the work which is to be embroidered will not work loose or sag during the operation of embroidering when the frame is placed in the embroidering machine.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the said invention consists, primarily, in the novel embroidery frame hereinafter set forth, and more especially in a novel work-retaining clamp therefor; and, the invention consists, furthermore, in the novel arrangements and combinations of the several devices and parts, as well as in the details of the construction of the same, all of which will be more fully described in the following specification, and then finally Specification of Letters Patent.

Serial No. 39,742.

embodied in the clauses of the claims which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a plan view of a fragmentary portion of an embroidery frame, and a face view of a clamping device therefor made according to and embodying the principles of the present invention, showing in connection therewith a corner-portion of a piece of work clamped in position in the frame, ready to be placed in an embroidery machine. Fig. 2 is a transverse section of the embroidery frame, said section being taken on line 2-2 in said Fig. 1, looking in the direction of the arrow :0, and illustrating in connection therewith, in elevation and in its clamped relation with the work, a work-retaining clamp made according to the principles of the present invention. Fig. 3 1s a transverse vertical section of the said parts, said section being taken on line 3-3 in said Fig. 1; and Fig. 4; is a similar sectional representation of the same parts, but showing the portions of the clamping device in the unclamped relation.

Similar characters of reference are employed in all of the above described Views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates the upper transverse bar of the embroidery frame, which may be made of wood, or any other suitable material, and which is provided at suitable intervals in its face with a plurality of receiving grooves or depressions, as 2, any number of which may be employed, according to the length of the embroidery frame.

The reference-character 3 indicates a number of U-shaped or channel-bars, and 4 indicates suitably-constructed clamping bars or members, pivoted, as at 5, with relation to said bars 3, all being preferably made according to and being arranged and operating, preferably, in the manner of the embroidery frame set forth in Letters-Patent No. 1,088,301, previously granted to me on February 24th, 1914. The reference-character 6 indicates the corner-portion of a piece of fabric, such as a handkerchief, which is to be embroidered, and 7 indicates one of the novel clamping devices made according to the present invention. A clamping device 7 is centrally disposed upon the Lil lower or under face, and substantially flush face of the bar 1. and is secured thereto by means of suitably disposed screws 10, or any other suitable fastening means. The said body-plate 8 is provided, preferably near its lower portion with an elongated opening 11, which is preferably of rectangular configuration. Extending forwardly, and slightly upwardly, from the lower marginal edge of the said body-plate 8 is a clamping lip 12. Suitably mounted upon said bod plate 8, at a suitable distance above the said elongated opening 11, by means of rivets 13, or other suitable fastening means, is a plate 11, which is provided with perforated pintle receiving cars 15, and in which is mounted a pintle l6. Suitably connected with the said pintle is the eye-portion 18 of a clamping swing-plate 17, said plate 17 being provided at the proper location with a rearwardly extending loop-shaped member or portion, as 19, which is adapted to be moved into said elongated opening 11 of the bodyplate 8, in the manner represented in Figs. 2 and 3 of the drawings, and has a for wardly extending portion 20 with which is connected a slightly downwardly extending clamping lip 21, the parts, when in their clamping positions, assuming the relative positions indicated in said Figs. 2 and 3, and the marginal edge 22 of the lip 21 assuming a position slightly back of the marginal edge 23 of the clamping lip 12 of the body-plate 8. To arrest the rearwardly swinging motion of the said swing-plate 17, at the proper time, and to bring the parts in the relative positions just above mentioned, the clamping lip 21 is made somewhat longer than the length of the opening 11 in the body-plate 8, so that the end-portions 2% of the lip 21 will engage with the face portions 25 of the body-plate 8, in the manner shown more particularly in Fig. 1 of the drawings.

Having in the foregoing described the general construction of the clamping device used in connection with the top-bar of the embroidery frame for clamping a portion of the fabric to be embroidered, I will now-describe the manner of its use in connection with tightening and stretching the fabric. The piece of fabric which is to be em broidered is properly stretched between and secured in position by the U-shaped or channel-bars 3 and the pivoted clamping bars or members 4 in the manner set forth in my said former Letters- Patent No. 1,088,301, herein above mentioned, and the swing plate iThavingbeen brought into the position indicated in said Fig. 4 of the drawings, the end of the laterally stretched' fabric is pulledtaut in the direction indi cated by the arrow 1 in Fig. l. The end 26 of the fabric is insertedin-theelongatcd opening of the body-plate 8, as shown more particularly in Fig. 3 of the drawings, and the swing-plate 17 brought into its clamping relation. whereby the marginal edge 22 of the lip 21 and the marginal edge of the lip 12 will firmly and securely retain the clamped portion of the fabric in its clamped relation, as will be clearly evident. To remove the retained portion of the fabric from the clamping device 7, all that is necessary is to apply a slight pressure upon the back of the loop-shaped member or portion 19 in the direction of the arrow 2, see Fig. 3,

whereby the swing-plate 17 will quickly spring into its released position.

I am fully aware that some changes may be made in the general arrangements and combinations of the several devices and parts, as well as in the: details of the con struction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specification and as defined in the clauses of the claims which are appended thereto. Hence, I do not limit my present invention to the exact arrangements and combinations of the several devices and parts, nor do I confine myself to the exact details of the construction of the said parts, as illustrated in the accompanying drawings.
